Count Me In is a nonprofit research organization that empowers patients to accelerate cancer research by sharing their samples, their clinical information, and their voices. With patient consent, all data collected by and generated through Count Me In projects are shared regularly with the research community (after being stripped of identifying information) through freely available scientific databases, so researchers anywhere can help rapidly accelerate the pace of discovery, expand our understanding of cancer, and develop new treatment strategies—breaking down silos that often exist in cancer research.
